TOURBOGRAPH PERPETUAL "Pour le Mérite"

Quintet of complications

The fifth Lange watch with the attribute “Pour le Mérite” combines a fusée-and-chain transmission with a tourbillon, chronograph, rattrapante function and perpetual calendar in the compact case of a wristwatch. This suite of complications makes the TOURBOGRAPH PERPETUAL “Pour le Mérite” a unique timepiece which comes in a limited edition of 50 watches.

The meticulous finissage of the 684 components of the calibre L133.1 – one of them is the entire chain – reflects the manufactory’s quest for perfection. In particular, the traditional black polish of the tourbillon bridge integrated in the dial illustrates this ambition: here, the time-consuming technique has been applied to curved surfaces for the first time. It requires not only extreme dexterity but also involves several hours of manual work.

We draw in towards the movement of the TOURBOGRAPH PERPETUAL "Pour le Mérite". Mystical close-ups of the movement and case follow. A huge pair of tweezers grabs a tiny pin that belongs to a tiny chain. More mystical pictures of movements follow. A tourbillon is inserted into the movement and vibrates. We flip over the case to the dial side of the watch and then back to the imposing movement side with the characteristic split-seconds clamp. After a few detail shots of the perpetual calendar indications, the watch finally presents itself completely in all its beauty.
